98249a57db gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

a8fca8d040 encodebin: Add APIs to set element properties on encoding profiles
User often want to set encoder properties on encoding profiles,
this introduces a way to easily 'preset' properties when defining the
profile. This uses GstStructure to define those properties the same
way it is done in `splitmux` for example as it makes simple to handle.

This also defines a more complex structure type where we can map a set
of properties to set depending on the muxer/encoder factory that has
been picked by EncodeBin so it is quite flexible.

1cead20777 encodebin: Fix and refactor smart encoding
It was not working properly and the implementation of the smartencoder
element was weird. This introduce a number of changes (which are all
in one single commit because they basically all work together and lead
to basically reimplementing the element):

* Make smartencoder a bin so that the reencoding chain of elements are
  inside of it instead of not having any parent. Those elements were not
  be visible when dumping the pipeline which was very confusing.
* Make encodebin create the right encoder with a capsfilter (and parser)
  to properly enforce the format specified by the user, and so that the
  encoder properties specified in the encoding profile are respected.
* Use `decodebin` to do the decoding instead of selecting a decoder
  ourself and not plug any parser etc...
* Ensure that negotiated format in the sinkpad of smart encoder is fixed
  through time when the user requested a non dynamic output
* Add a parser at the beginning of the smart encoder
* Handle errors when reencoding

d297c4447d encoding: Use G_DECLARE_FINAL_TYPE
Note that we didn't do it for encodebin, as it has a class struct. We
_could_ techincally use `G_DECLARE_DERIVABLE_TYPE()` for that one, but
that would mean also using a private struct, which is even more work for
no gain.

a724f9ddfb encodebin: Ensure that a single segment is pushed into encoders
Following the [design document] encodebin needs to handle sources that
output multiple streams, for that purpose and to make it simpler,
we ensure that a single segment is outputted to the encoders by using
an `identity single-segment=true` at the beginning of streams chains.

Added API to enable or disable the use of that new feature.
Added support for the encoding profile parser for that new property,
keeping backward compatibility

9af8516873 streamcombiner: Forward upstream force-key-unit events to all sinkpads
streamcombiner element forwards a upstream event only to one sinkpad.
When the streamcombiner is used with encodebin, the sinkpad
corresponding to pass-through path is configured before that of encoder,
and therefore streamcombiner forwards upstream events only to
the firstly configured one (i.e., pass-through path).

0314b482f3 Don't pass default GLib marshallers for signals
By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.

Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.

9ce8cf89ba encodebin: Also lock input caps when dynamic output is disabled
With the way caps negotiation work in encoders, the only way to ensure
that no downstream renegotiation is done in the encoder is to also lock
upstream caps. Anyway with the current behavior upstream of encoders
*require* to handle any file format so locking upstream format should
be safe.

25e0b77bbe encodebin: Don't try rate adjustment before the first buffer
With both audiorate and videorate, it seems more sensible to apply rate
adjustments after the first buffer appears. For example, with v4l2src,
there is often a small delay before the first video buffer turns up, and
this can cause a stuttery start because of videorate trying to ensure a
perfect stream.

5c4f4ac1bd Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.
